In a statement issued on Tuesday, the NRL said Earl faces allegations of multiple anti-doping rule violations - including a number of use and trafficking allegations.

Chief Operating Officer Jim Doyle said that the NRL's Anti-Doping Tribunal would now be convened to offer Earl a hearing to determine the charges.

We acted quickly to ensure a player who admitted using performance enhancing drugs was not playing in our competition. We make no apologies for taking this stance.

Doyle said Earl had admitted injecting CJC-1295 on many occasions in 2011.

"Further, in relation to conduct alleged to have occurred in 2012 and 2013, he faces in the NRL's Anti-Doping Tribunal allegations of anti-doping rule violations of trafficking or attempted trafficking in other prohibited substances including the growth hormone Somatropin, Selective Androgen Receptor Modulators (SARMS), the anabolic agent Clenbuterol and the testosterone blend Sustanon," the statement said.

The NRL's anti-doping policy provides that the penalty for using banned substances is up to two years and for trafficking or attempted trafficking it is a minimum four years up to lifetime ineligibility.

"Mr Earl has publicly confirmed that he has been placed on ASADA's Register of Findings and the NRL is now proposing to move to a hearing before its Anti-Doping Tribunal," Doyle said.

"There is no place for drugs in our sport and we are comfortable with the way we have handled the matter in the best interests of the integrity of the NRL competition."

NRL acted on information provided

Doyle said the NRL's Anti-Doping Policy requires the NRL to act where it comes into possession of information that might constitute an anti-doping rule violation.

"We acted quickly to ensure a player who admitted using performance enhancing drugs was not playing in our competition. We make no apologies for taking this stance."

After Earl was stood down he engaged in discussions with ASADA in relation to a possible discount in penalty to reflect substantial assistance he may have provided to ASADA.

Those discussions have concluded and Earl has been placed on ASADA's Register of Findings and the NRL is able to offer him a hearing.

Doyle said the NRL would not waiver in its determination to deal with breaches of the Anti-Doping policy.

"The use of banned substances goes to the heart of our game and we will do everything in our power to deal with those who breach our rules," he said.
